Description

DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTIONTECHNICAL FIELD TO WHICH THE INVENTION REFERS

La présente invention concerne de manière générale les appareillages électriques qui comprennent un quelconque mécanisme d'appareillage, tel que par exemple un mécanisme d'interrupteur ou de prise de courant, rapporté dans une boîte à encastrer dans une paroi quelconque, dans un boîtier ou dans une goulotte électrique à rapporter en saillie d'une telle paroi.The present invention generally relates to electrical apparatus which comprises any apparatus mechanism, such as for example a switch or socket mechanism, mounted in a box for mounting in any wall, in a housing or in a an electrical chute to project projecting from such a wall.

Elle concerne en particulier appareillage électrique comprenant une plaque enjoliveur se présentant sous la forme d'un cadre qui entoure au moins une touche de commande accessible à l'usager pour l'actionnement d'au moins un mécanisme d'appareillage, et des moyens d'éclairement propres à l'éclairage d'une zone de façade dudit appareillage.It relates in particular to electrical equipment comprising a trim plate in the form of a frame which surrounds at least one control button accessible to the user for the actuation of at least one fitting mechanism, and means of illumination suitable for illuminating a façade area of said apparatus.

L'invention trouve une application particulièrement avantageuse dans la réalisation d'un interrupteur électrique à fonction lumineuse, visible dans la pénombre.The invention finds a particularly advantageous application in the production of an electric switch with a light function, visible in dim light.

ARRIERE-PLAN TECHNOLOGIQUEBACKGROUND

On connaît déjà des documents FR 2 790 865 , GB 2 083 708 et EP 1 467 387 des appareillages électriques du type précité qui intègrent une fonction lumineuse pour être repérés dans une pièce sombre et/ou indiquer à l'usager leur état de fonctionnement (ouvert ou fermé).We already know documents FR 2,790,865 , GB 2,083,708 and EP 1 467 387 electrical equipment of the aforementioned type which incorporates a light function to be located in a dark room and / or indicate to the user their operating status (open or closed).

Dans ces appareillages électriques déjà connus, les moyens d'éclairement comprennent une source lumineuse (une diode ou une ampoule à filaments) disposées à l'intérieur du boîtier d'appareillage pour éclairer directement ou indirectement la touche de commande accessible à l'usager.In these electrical equipment already known, the illumination means comprise a light source (a diode or a filament bulb) disposed inside the equipment box to illuminate directly or indirectly the control key accessible to the user.

Cette source lumineuse est montée sur un support dédié et est raccordée électriquement au mécanisme d'appareillage.This light source is mounted on a dedicated support and is electrically connected to the fitting mechanism.

En outre, dans ces appareillages électriques déjà connus, les moyens d'éclairement comprennent des moyens de guidage ou de réflexion de la lumière embarqués dans la touche de commande ou positionnés juste en dessous de cette touche de commande. Ces moyens de guidage ou de réflexion permettent soit de guider la lumière émise par la source lumineuse, soit d'accentuer le pouvoir lumineux de la source lumineuse sur une zone précise de la touche de commande.In addition, in these electrical equipment already known, the illumination means comprise light guide or reflection means embedded in the control key or positioned just below this control key. These guide or reflection means make it possible either to guide the light emitted by the light source or to accentuate the luminous power of the light source on a specific area of the control button.

En particulier, on connaît du document EP 1 385 185 un appareillage électrique dans lequel la plaque enjoliveur comporte en façade une zone d'écriture éclairée. Pour cela la plaque enjoliveur comporte sur un de ses côtés un logement pour un guide de lumière apte à guider la lumière émise par une source de lumière vers une feuille d'inscription rapportée en façade de ladite plaque. Ici, la source de lumière qui fait partie des moyens d'éclairement est logée dans le boîtier de l'appareillage.In particular, document is known EP 1 385 185 an electrical apparatus in which the trim plate has an illuminated writing area on the front. For this purpose the trim plate has on one of its sides a housing for a light guide adapted to guide the light emitted by a light source to an inscription sheet attached to the front of said plate. Here, the light source which is part of the illumination means is housed in the housing of the apparatus.

On connaît également du document WO 03/071565 un appareillage électrique dont la façade porte des inscriptions éclairées. Pour cela, il est prévu en arrière de la façade un guide de lumière adapté à diffuser la lumière provenant d'une source de lumière externe, l'ensemble du guide de lumière et de la source de lumière étant placé dans le socle de l'appareillage.Document is also known WO 03/071565 an electrical apparatus whose facade bears illuminated inscriptions. For this purpose, there is provided behind the facade a light guide adapted to diffuse the light from an external light source, the entire light guide and the light source being placed in the base of the equipment.

De tels appareillages électriques présentent plusieurs inconvénients.Such electrical equipment has several disadvantages.

Tout d'abord, les moyens d'éclairement de ces appareillages électriques sont complexes à monter dans le boîtier d'appareillage et ils ne sont pas accessoirisables.First, the lighting means of these electrical equipment are complex to mount in the equipment box and they are not accessorizable.

En outre, dans de tels appareillages, la source lumineuse des moyens d'éclairement est difficilement accessible dans le boîtier d'appareillage. Ainsi, il est notamment difficile de récupérer une partie substantielle du flux lumineux émis par la source lumineuse pour la guider jusqu'à la touche de commande ou la plaque enjoliveur afin d'obtenir un éclairage correct de celle-ci.In addition, in such devices, the light source of the illumination means is difficult to access in the equipment box. Thus, it is particularly difficult to recover a substantial portion of the luminous flux emitted by the light source to guide it to the control button or the trim plate to obtain a correct illumination thereof.

Enfin de tels moyens d'éclairement ne permettent pas de former un halo de lumière autour de l'appareillage électrique correspondant.Finally, such illumination means do not make it possible to form a halo of light around the corresponding electrical equipment.

Par ailleurs, le document DE 200 19 668 décrit un appareillage électrique complexe dans lequel la plaque enjoliveur et le support d'appareillage sont assemblés et positionnés sur une plaque frontale éclairée en façade au moyen de diodes montées sur une sous plaque pour canaliser le flux lumineux émis vers l'avant dudit appareillage.In addition, the document DE 200 19 668 describes a complex electrical apparatus in which the trim plate and the equipment support are assembled and positioned on a front illuminated front plate by means of diodes mounted on a sub plate to channel the luminous flux emitted towards the front of said apparatus.

Sur les figures 1 et 2, on a représenté un appareillage électrique 100 présentant une fonction lumineuse notamment pour être visible dans la pénombre ou indiquer à l'usager l'état de fonctionnement dudit appareillage.On the Figures 1 and 2 , there is shown an electrical apparatus 100 having a light function in particular to be visible in the penumbra or indicate to the user the operating state of said apparatus.

Cet appareillage électrique 100 comprend de manière connue en soi un support 110 destiné à être fixé à une boîte à encastrer dans une paroi quelconque, par exemple, une paroi alvéolaire, ou à un boîtier ou encore à une goulotte à rapporter en saillie sur une telle paroi.This electrical apparatus 100 comprises, in a manner known per se, a support 110 intended to be fixed to a box for embedding in any wall, for example, a honeycomb wall, or to a housing or to a trough to be projected on such a wall.

Le support 110 sert au montage à l'intérieur de la boîte, du boîtier ou de la goulotte d'un ou plusieurs mécanismes d'appareillage 130, tel qu'un mécanisme d'interrupteur, de prise de courant, de prise de téléphone, de disjoncteur.The support 110 is used to mount inside the box, the housing or the chute of one or more equipment mechanisms 130, such as a switch mechanism, socket, telephone jack, circuit breaker.

Il se présente ici sous la forme d'un cadre plat en matière plastique ou métallique, de forme carrée par exemple.It is here in the form of a flat frame made of plastic or metal, square for example.

Le cadre est défini entre un bord périphérique extérieur et un bord périphérique interne qui délimite une ouverture centrale également de forme carrée à l'intérieur duquel est monté le socle du mécanisme d'appareillage 130 correspondant.The frame is defined between an outer peripheral edge and an inner peripheral edge which delimits a central opening also of square shape within which is mounted the base of the corresponding apparatus mechanism 130.

L'ouverture centrale du support est destinée à accueillir un ou plusieurs socles de mécanisme d'appareillage.The central opening of the support is intended to accommodate one or more pedestals of equipment mechanism.

Ici elle permet d'accueillir un socle deux modules dont la façade de forme carrée remplit la surface de l'ouverture centrale.Here it can accommodate a base two modules whose square-shaped facade fills the surface of the central opening.

Pour le montage de chaque socle de mécanisme d'appareillage 130, l'ouverture centrale du support 110 est bordée sur ses quatre côtés de moyens de montage ici non représentés, par exemple des moyens d'encliquetage.For the mounting of each instrument mechanism base 130, the central opening of the support 110 is bordered on its four sides by mounting means not shown here, for example latching means.

L'appareillage électrique 100 comporte également une plaque enjoliveur 120 se présentant également sous la forme d'un cadre, de forme carrée, qui entoure au moins une touche de commande 131 accessible à l'usager pour l'actionnement d'au moins un mécanisme d'appareillage, ici le mécanisme d'appareillage 130 supporté par le support 110.The electrical apparatus 100 also comprises a trim plate 120 also in the form of a frame, of square shape, which surrounds at least one control key 131 accessible to the user for the actuation of at least one mechanism apparatus, here the apparatus mechanism 130 supported by the support 110.

La plaque enjoliveur 120 présente une partie de façade plane bordée par un rebord périphérique 120A qui forme la tranche de celle-ci.The trim plate 120 has a flat front portion bordered by a peripheral flange 120A which forms the edge thereof.

Par ailleurs, l'appareillage électrique 100 comporte des moyens d'éclairement 200 (voir figures 3 à 6) propres à l'éclairage d'une zone de façade dudit appareillage pour que celui-ci soit visible dans la pénombre ou indique à l'usager son état de fonctionnement.Moreover, the electrical equipment 100 comprises illumination means 200 (see FIG. Figures 3 to 6 ) suitable for lighting a façade area of said apparatus so that it is visible in the dark or indicates to the user its operating condition.

Comme le montrent les figures 3 à 6, selon l'invention, ces moyens d'éclairement 200 sont embarqués sur la plaque enjoliveur 120 et sont adaptés à éclairer la tranche 120A de celle-ci (voir figure 2).As shown by Figures 3 to 6 according to the invention, these illumination means 200 are embedded on the embellisher plate 120 and are adapted to illuminate the wafer 120A thereof (see figure 2 ).

Comme le montre plus particulièrement la figure 2, ces moyens d'éclairement sont agencés de manière à pouvoir former un halot lumineux 1 autour de l'appareillage électrique et plus particulièrement autour de la plaque enjoliveur 120.As shown more particularly in figure 2 these illumination means are arranged so as to form a luminous halftone around the electrical equipment and more particularly around the hub plate 120.

Les moyens d'éclairement 200 sont rapportés ici sur la face arrière de ladite plaque enjoliveur (voir figures 3 à 6). Ils sont logés dans l'épaisseur de ladite plaque enjoliveur 120, le rebord périphérique 120A et la partie de façade de ladite plaque enjoliveur formant intérieurement un logement destiné à accueillir lesdits moyens d'éclairement 200.The illumination means 200 are reported here on the rear face of said hub plate (see Figures 3 to 6 ). They are housed in the thickness of said trim plate 120, the peripheral rim 120A and the front portion of said trim plate internally forming a housing for receiving said illumination means 200.

Ici, préférentiellement, les moyens d'éclairement 200 comprennent une source lumineuse et un guide optique 210 adaptés à guider le flux lumineux émis par la source lumineuse jusqu'à la tranche 120A de ladite plaque enjoliveur 120.Here, preferentially, the illumination means 200 comprise a light source and an optical guide 210 adapted to guide the luminous flux emitted by the light source to the edge 120A of said trim plate 120.

Préférentiellement, la source lumineuse comprend des diodes électroluminescentes (non représentées sur les figures) raccordées à un circuit imprimé supporté par une plaque support 220.Preferably, the light source comprises light-emitting diodes (not shown in the figures) connected to a printed circuit supported by a support plate 220.

Le guide optique 210 et la plaque support 220 du circuit imprimé auquel sont raccordées les diodes électroluminescentes présentent également une forme de cadre carré adaptée à la forme de la plaque enjoliveur 120.The optical guide 210 and the support plate 220 of the printed circuit to which the light-emitting diodes are connected also have a square frame shape adapted to the shape of the trim plate 120.

Avantageusement, le guide optique 210 peut présenter sur sa tranche des stries pour diffuser la lumière.Advantageously, the optical guide 210 may have striations on its edge to diffuse the light.

Il est réalisé en matière plastique moulée comme par exemple du polycarbonate transparent ou du polymétacrylate de méthyle acrylonitrile transparent.It is made of molded plastic such as transparent polycarbonate or transparent methylmethyl acrylonitrile polymethacrylate.

Comme le montre plus particulièrement la figure 4, le guide optique 210 comporte des moyens de montage, ici des moyens de rainure 210A, pour le montage de la plaque support 220 du circuit imprimé.As shown more particularly in figure 4 , the optical guide 210 comprises mounting means, here groove means 210A, for mounting the support plate 220 of the printed circuit.

En outre, le guide optique 210 sur lequel est montée la plaque support 220 de circuit imprimé peut être soudé par ultrasons à la plaque enjoliveur 120 pour former un ensemble très rigide.In addition, the optical guide 210 on which the printed circuit support plate 220 is mounted can be ultrasonically welded to the trim plate 120 to form a very rigid assembly.

Le guide optique 210 est capable de guider la lumière émise par les diodes électroluminescentes pour diffuser cette lumière au travers de la tranche 120A de la plaque enjoliveur et réaliser un halot lumineux 1 autour de cette plaque enjoliveur comme cela est représenté plus particulièrement sur la figure 2.The optical guide 210 is capable of guiding the light emitted by the light-emitting diodes to diffuse this light through the edge 120A of the trim plate and to make a luminous halftle around this trim plate, as shown more particularly in FIG. figure 2 .

Selon le mode de réalisation représenté sur la figure 1, le circuit imprimé auquel sont connectées les diodes électroluminescentes peut être alimenté au courant par des conducteurs électriques 12,13 connectés aux bornes de connexion du mécanisme d'appareillage lui-même connecté par des conducteurs électriques 11,12 au réseau d'alimentation électrique.According to the embodiment shown on the figure 1 , the printed circuit to which the light-emitting diodes are connected can be supplied with current by electrical conductors 12, 13 connected to the connection terminals of the switchgear mechanism itself connected by electrical conductors 11, 12 to the power supply network.

En variante, on peut prévoir d'alimenter en courant ledit circuit imprimé par des accumulateurs d'énergie 300 (des piles) logés dans ladite plaque enjoliveur (voir figure 5). On peut également prévoir comme cela est représenté sur la figure 6 que le circuit imprimé soit alimenté en courant par un système à induction 300' avec un émetteur 301' alimenté en courant via les bornes de connexion du mécanisme d'appareillage 130 et un récepteur 302' logé dans la plaque enjoliveur 120.As a variant, it is possible to supply said printed circuit with power by energy accumulators 300 (batteries) housed in said trim plate (see FIG. figure 5 ). It can also be expected as shown on the figure 6 that the printed circuit is supplied with current by an induction system 300 'with a transmitter 301' supplied with current via the connection terminals of the equipment mechanism 130 and a receiver 302 'housed in the trim plate 120.

Ces deux moyens précités d'alimentation électrique du circuit imprimé sont particulièrement avantageux dans le sens où ils sont au moins pour partie embarqués sur la plaque enjoliveur et permettent une facilité de montage de l'appareillage électrique.These two aforementioned power supply means of the printed circuit are particularly advantageous in the sense that they are at least partly embedded on the trim plate and allow easy assembly of the electrical equipment.

Avantageusement, la partie de façade de la plaque enjoliveur 120 est une partie opaque et ladite plaque enjoliveur comprend une partie arrière translucide formant au moins une partie de la tranche 120A de la plaque enjoliveur.Advantageously, the front portion of the embellisher plate 120 is an opaque portion and said trim plate comprises a translucent rear portion forming at least a portion of the wafer 120A of the trim plate.

Cette partie arrière translucide peut être rapportée ou surmoulée sur la face arrière de la partie de façade opaque qui peut s'étendre sur un côté de la plaque enjoliveur de telle sorte que les moyens d'éclairement éclairent trois côtés sur quatre de cette plaque. La partie de façade est avantageusement réalisée en matière métallique tandis que la partie arrière est réalisée en matière plastique moulée, elle peut être encliquetée sur la face arrière de cette partie de façade.This translucent rear portion may be attached or overmolded on the rear face of the opaque facade portion which may extend on one side of the trim plate so that the illumination means illuminate three sides of four of the plate. The front portion is advantageously made of metallic material while the rear portion is made of molded plastic material, it can be snapped onto the rear face of this facade part.
